Learn PowerPoint 2011 for Mac: Crop Pictures (Mask to Shape)

You already learned how to play with all the different Crop options in PowerPoint 2011 -- all except the Mask to Shape option, which we explain in this tutorial. Mask to Shape can be immensely helpful if you want any picture to show contained within a shape. In other words, you start with a conventional, rectangular picture and end up a picture that's not contained within a non-rectangular shape.
